[0002] Highway and railway sound barrier is a specially designed facility, aiming at reducing the noise generated by highway and railway traffic on the surrounding environment and residents. The sound barrier inserts a facility between the sound source and the receiver, so that the sound wave propagation has a significant additional attenuation, thereby weakening the noise effect in the area where the receiver is located.
[0003] However, the existing highway and railway sound barrier still has some shortcomings in use. The existing barrier structure mostly only has single sound insulation or vibration isolation function, and the function is relatively single.

Moreover, the structure between the barrier and the frame is mostly complex, the installation workload is large, and it is not convenient to install.

Although the glass wool has good sound insulation effect, it is difficult to assemble during the assembly process. At the same time, the glass wool is also easy to absorb water, which causes the internal water of the sound barrier plate to be damaged for a long time. UTILITY MODEL CONTENTS
